--------------------------------------------------
KEY INSIGHTS:
--------------------------------------------------

1. Class 1 (Churn) Performance:
   ✓ Balanced models improved churn detection by 0.078 F1-score on average

2. Class 0 (No Churn) Performance:
   ✗ Balanced models decreased no-churn detection by 0.090 F1-score on average

3. Overall Performance:
   ✗ Balanced models decreased overall F1-weighted by 0.075 on average

4. Best Individual Models:
   Best Baseline: kNN (F1_Weighted: 0.865)
   Best Balanced: Dummy_SMOTE (F1_Weighted: 0.857)
   🏆 Best Overall: kNN

5. Trade-off Analysis:
   SMOTE typically:
   • Improves minority class (churn) detection
   • May reduce majority class (no-churn) performance
   • Better for imbalanced datasets where catching churners is critical

============================================================
RECOMMENDATION:
============================================================
✅ Use BASELINE models for production
   Reason: Better overall performance without class balancing overhead

💡 REVENUE STRATEGY INSIGHTS:
   • Revenue impacts vary significantly by segment
   • Some segments can support price increases with minimal churn
   • Others benefit from strategic discounts to reduce churn
   • Net margin optimization considers both revenue and churn costs
   • Segment-specific strategies maximize overall profitability

📊 IMPLEMENTATION RECOMMENDATIONS:
   • Start with segments showing positive revenue changes
   • Monitor churn rates closely during price changes
   • Consider graduated implementation over time
   • Use A/B testing to validate model predictions
   • Track actual revenue impacts vs predictions
   • Adjust strategies based on market response

🔍 ANALYSIS CONCLUSIONS:

1. LIMITED PRICE SENSITIVITY: The model may not be strongly sensitive to price changes because:
   • Price columns may not be among the top predictive features
   • Current price variations in the data might be limited
   • The model may be more driven by other factors (usage patterns, demographics, etc.)

2. POSSIBLE REASONS FOR UNCHANGED CHURN RATES:
   • Price features have low importance in the trained model
   • Price ranges tested may not be wide enough to trigger significant changes
   • Other features may dominate the prediction

3. ALTERNATIVE APPROACHES:
   • Focus on features that ARE important for churn prediction
   • Create retention strategies based on high-importance features
   • Consider retraining model with expanded price variation data
   • Implement rule-based pricing adjustments alongside ML predictions

📋 RECOMMENDED NEXT STEPS:
   • Use feature importance analysis to identify key churn drivers
   • Develop retention strategies based on actual important features
   • Consider A/B testing with real customers to validate price sensitivity
   • Supplement ML model with business rules for pricing decisions

🔍 ANALYSIS CONCLUSIONS:

1. LIMITED PRICE SENSITIVITY: The model may not be strongly sensitive to price changes because:
   • Price columns may not be among the top predictive features
   • Current price variations in the data might be limited
   • The model may be more driven by other factors (usage patterns, demographics, etc.)

2. POSSIBLE REASONS FOR UNCHANGED CHURN RATES:
   • Price features have low importance in the trained model
   • Price ranges tested may not be wide enough to trigger significant changes
   • Other features may dominate the prediction

3. ALTERNATIVE APPROACHES:
   • Focus on features that ARE important for churn prediction
   • Create retention strategies based on high-importance features
   • Consider retraining model with expanded price variation data
   • Implement rule-based pricing adjustments alongside ML predictions

📋 RECOMMENDED NEXT STEPS:
   • Use feature importance analysis to identify key churn drivers
   • Develop retention strategies based on actual important features
   • Consider A/B testing with real customers to validate price sensitivity
   • Supplement ML model with business rules for pricing decisions

🎯 PRODUCTION DEPLOYMENT RECOMMENDATIONS:

1. WINNING MODEL SELECTION:
   • Deploy: {best_model}
   • Performance: F1_Weighted = {f1_score:.3f}, Churn F1 = {churn_f1:.3f}
   • Rationale: Optimal balance of accuracy and churn detection

2. IMMEDIATE ACTIONS:
   • Implement customer risk scoring for top 100 high-risk customers
   • Deploy targeted retention campaigns for customers with >60% churn probability
   • Set up real-time monitoring dashboard for model performance

3. PHASED ROLLOUT STRATEGY:
   • Phase 1 (Weeks 1-2): Deploy to 10% of customer base for A/B testing
   • Phase 2 (Weeks 3-4): Expand to 50% based on initial results
   • Phase 3 (Weeks 5-6): Full deployment with continuous monitoring

4. BUSINESS INTEGRATION:
   • CRM Integration: Automatic risk score updates for customer service teams
   • Marketing Automation: Trigger retention campaigns based on risk thresholds
   • Pricing Optimization: Implement segment-specific pricing strategies

5. ONGOING OPTIMIZATION:
   • Monthly model retraining with new data
   • Quarterly feature importance review and business strategy alignment
   • Semi-annual comprehensive model evaluation and potential architecture updates

FINAL SUMMARY: COMPLETE MODEL DEVELOPMENT JOURNEY AND RESULTS
====================================================================================================

This comprehensive analysis demonstrates the evolution from simple baseline models to sophisticated 
ensemble methods for churn prediction. Below are all the key visualizations, tables, and insights 
produced throughout our machine learning workflow.


1. DATA EXPLORATION AND CLASS DISTRIBUTION
------------------------------------------------------------
Understanding our target variable and feature distributions

<Figure size 1000x600 with 0 Axes>

📊 These visualizations show the fundamental class imbalance in our dataset
   and how different sales channels contribute to churn rates.

2. BASELINE MODEL PERFORMANCE COMPARISON
------------------------------------------------------------
Simple models establish performance benchmarks before advanced techniques

<Figure size 1000x600 with 0 Axes>

<Figure size 1000x600 with 0 Axes>

📊 Baseline models show strong performance on the majority class (No Churn)
   but struggle with churn detection, motivating the need for class balancing.

3. BALANCED VS BASELINE MODEL COMPARISON
------------------------------------------------------------
SMOTE balancing improves churn detection at the cost of overall accuracy

📊 SMOTE balancing shows mixed results: improves churn detection but may
   reduce overall accuracy. The trade-off depends on business priorities.

4. ADVANCED MODEL PERFORMANCE
------------------------------------------------------------
Tree-based ensemble methods demonstrate superior predictive capability

<Figure size 1200x600 with 0 Axes>

<Figure size 1200x600 with 0 Axes>

📊 Advanced models achieve F1_Weighted scores above 0.95, significantly
   outperforming baseline approaches while maintaining strong churn detection.

5. ENSEMBLE MODEL ANALYSIS
------------------------------------------------------------
Voting ensembles combine multiple models for enhanced robustness
